We have SQL 2005 with DB in Full recovery mode.
We have full DB backup done early every day followed by differential backup at regular intervals during the day.
After working for years, for unknown reason the differential backup is failing with error below:
Msg 3035, Level 16, State 1, Line 1
Cannot perform a differential backup for database "xx", because a current database backup does not exist. Perform a full database backup by reissuing BACKUP DATABASE, omitting the WITH DIFFERENTIAL option.
Msg 3013, Level 16, State 1, Line 1
BACKUP DATABASE is terminating abnormally.
The funny thing is that a full backup is compeleting successfully before the differential one runs.
Thoug there are a few links on this, I haven't come across a definite proposed working solution.
Can the MS SQL evangelists please advise !!!
Thank you.
